摘　　要：建立液相色谱分离、电喷雾四极杆质谱测定饮用水中溴酸盐和高氯酸盐的方法。使用XterraTMC18色谱柱,以乙腈-四丁基氢氧化铵溶液为流动相分离,选择离子检测。溴酸盐和高氯酸盐的线性范围均为1.0～200.0ng/mL,方法检出限均为1.0ng/mL。A method for the determination of bromate and perchlorate in drinking water was established by high performance liquid chromatography coupled to electrospray ionization quadrupole mass spectrometry （HPLC/ESI-MS）. The chromato-graphic separation column used was a Waters XterraTM C18 column, and the binary mobile phase used consisted of acetonitrile as mobile phase A and 1.5 mmol/L aqueous solution of tetrabutyl ammonium hydroxide solution as mobile phase B. Both analytes were detected in the selected ion monitoring （SIM） mode. The developed calibration curve showed good linearity over the concentration range from 1 to 200 ng/mL. The detection limit was 1 ng/mL for both bromate and perchlorate.
